Abstract
A distributed acoustic system (DAS) may include at least one laser that that transmits at least one continuous wave (CW) light, a pulser disposed after and optically connected to the at least one laser to form a light pulse, and a splitter optically connected to the pulser to optically split the light pulse into a plurality of light pulses. The DAS may further include a proximal circulator optically connected to a first output of the splitter, a distal circulator optically connected to the proximal circulator, and a sensor fiber attached to the distal circulator. A method for using the DAS may include setting a pulse power for a laser, transmitting one or more light pulses from the laser into a distributed acoustic system (DAS), and measuring a signal to noise ratio (SNR) from a backscatter light created within the fiber optical cable and the sensor fiber.
